1. thats the past! nowadays everyone can live without him
2. he got credits when his bypass worked! after that he didnt get credits anymore. i think its clear why. why should anyone give credits for his (without any bypass) working hack to someone who created a bypass in the PAST?
3. his full bypass WAS his modified client

he modified the client to bypass HS. and it was no big deal.
4. you are wrong. i have. and many others do, too. its just not public.
